A new species of tree cricket, Neoxabea mexicanasp. nov., is described from northeast Mexico. Although it has morphological similarities to two other species found in Mexico, there are distinguishing characters, such as a well-developed tubercle on the pedicel, black markings on the maxillary palpi, one of the two pairs of spots on the female wings positioned at the base of the wings, stridulatory teeth count, and the pulse rate of the male calling song. The calling song description and pre-singing stuttering frequencies are provided. Character comparisons that rule out other species in the genus are presented. The common name given to this new species is Mexican tree cricket. Sound recordings and video are available online. We also make some clarification of the status of Neoxabea formosa (Walker, 1869), described as Oecanthus formosus, and present a key of Neoxabea in North and Central America.

Bush Cricket

The genus Saga is a genus of generally large predatory bush-cricket species. It includes 13 taxa in the Palaearctic region. In this research, eight species belonging to Saga (Tettigoniidae, Saginae) were sampled during field studies in different regions of Anatolia of Turkey between 2010 and 2018 (except one specimen). The bioacoustic parameters of these species recorded during the field or in laboratory conditions and the male calling song descriptions, as well as the oscillographic illustrations and distribution maps are given. A new population of Saga found from the South-Eastern Taurus (Hakkari province), which is affiliated to a new species and shows similarity to S. ephippigera, along with the morphological and bioacoustical descriptions of Saga hakkarica sp. n. Şirin & Taylan from Turkey, are also given. The relationships between the new species and the closest taxa are discussed using morphological and bioacoustical characters. The structural investigations of the male calling songs reveal three different bioacoustic groups affiliated to eight Anatolian Saga species; as (i) Ephippigera group (S. syriaca + (S. ephippigera + Saga hakkarica), (ii) Natoliae group (S. natoliae + (S. beieri + (S. longicaudata + S. puella) and (iii) S. cappadocica.

The morphology and pair-forming acoustic signals of Isophya sicula sp. n., a new phaneropterine bush-cricket species from the Eastern Carpathians (Romania) is described. The species is morphologically similar to I. posthumoidalis and I. camptoxypha, but the male calling song differs clearly from the songs of those species. The male calling song is a long series of evenly repeated, very short syllables. Syllables are much shorter than in I. camptoxypha, and the song is composed from only one syllable type differently from I. posthumoidalis, where the male calling song is composed of two syllable types. Pair formation is achieved during an acoustic duet. The delay of female response (40–70 ms) is shorter than in I. camptoxypha and I. posthumoidalis. Basic descriptive statistics of sonometric and morphometric characters of the new species as well as SEM photos of the male stridulatory file and female stridulatory bristles are presented.

A New Species

A new species for the genus Isophya, I. bumerangoides, is described from the Northeastern Black Sea Region of Turkey. Thenew species differs from closely related species in some aspects of morphology, mainly in male and female genitalia. Illustra-tions of external morphological characters and male and female songs are provided. Additional data on male calling song andfemale song of closely related bush-cricket Isophya rizeensis Sevgili, 2003 are also given. Scanning Electron Microscopeimages of stridulatory file of the other related species I. redtenbacheri Adelung, 1907 are provided. I. bumerangoides clearlybelongs to I. amplipennis group. Our bioacoustic results suggest that within the genus Isophya, changes in calling song seem to appear more slowly than those in external morphological characters as in most tettigoniid.

Sources Of Variation

Genetic and environmental sources of variation in the temporal patterning of song structure may be important variables influencing male field cricket reproductive success. Song structure in both field and laboratory populations of Gryllus pennsylvanicus was examined to assess possible sources of variation. Factors examined included temperature, male age, body mass, time of day, and male spacing patterns. Temperature was positively correlated with pulse rate and negatively correlated with interchirp interval for both field and laboratory populations. Temperature was negatively correlated with chirp duration only in the field population. Calling song structure did not vary with male age or mass. Time of day had a significant effect on the song parameters examined, even when data were corrected for temperature differences. Males calling in the morning had faster pulse rates and shorter chirp durations than males recorded at night time. Male spacing patterns also influenced calling; isolated males had longer intervals between consecutive chirps than clumped males. Data are discussed in terms of acoustical competition between males and female choice.

Phase Differences

Female field crickets use phonotaxis to locate males by their calling song. Male song production and female behavioural sensitivity form a pair of matched frequency filters, which in Gryllus bimaculatus are tuned to a frequency of about 4.7 kHz. Directional sensitivity is supported by an elaborate system of acoustic tracheae, which make the ears function as pressure difference receivers. As a result, phase differences between left and right sound inputs are transformed into vibration amplitude differences. Here we critically tested the hypothesis that acoustic properties of internal transmissions play a major role in tuning directional sensitivity to the calling song frequency, by measuring tympanal vibrations as a function of sound direction and frequency. Rather than sharp frequency tuning of directional sensitivity corresponding to the calling song, we found broad frequency tuning, with optima shifted to higher frequencies. These findings agree with predictions from a vector summation model for combining external and internal sounds. We show that the model provides robust directional sensitivity that is, however, broadly tuned with an optimum well above the calling song frequency. We therefore advocate that additional filtering, e.g. at a higher (neuronal) level, significantly contributes to frequency tuning of directional sensitivity.
